The scatterplot shows the numbers of countries that participated in the Summer Olympic Games from 1948 to 1992. Two years, 1976 and 1980, are not included. Based on the scatterplot, what is the best prediction of the number of countries that participated in the Olympics in 1980? HELP ASAP A. 120
B. 60
C. 135
D. 56

What is the pattern in the values as the exponents increase?

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.

Select the margin of error that corresponds to the sample mean that corresponds to each population: a population mean of 360, a standard deviation of 4, and a margin of error of 2.5%
